It was previously announced that the musical adaptation will premiere in fall 2017 in Washington, D.C.

Tony Award-winning Book of Mormon director Casey Nicholaw has been tapped to direct and choreograph a developmental lab of the stage adaptation of Tina Fey’s 2004 hit comedy film Mean Girls, according to an Equity casting notice.

According to the notice, the four-week lab will be held April 3-29, 2017; auditions for male and female singers will be held December 6 at Pearl Studios. Mary-Mitchell Campbell will be the lab’s musical director, and casting is by Telsey + Company/Bethany Knox, CSA. Thompson Turner Productions is the general manager.

As previously reported, the adaptation of the film Mean Girls, which starred actress Lindsay Lohan as a high school transfer student trying to navigate teenage social cliques, will have its world premiere in fall 2017 in Washington, D.C.

The news was announced October 3—the day fans have dubbed Mean Girls day, in reference to a line in the film. Tony Award-nominated Legally Blonde lyricist Nell Benjamin is collaborating with Golden Globe winner Fey and Fey’s husband, composer Jeffrey Richmond. Fey told the Tribeca Film Festival crowd that the pregnancy of Unbreakable Kimmy Schmidt star Ellie Kemper has given her the chance to focus on the new musical.

Mean Girls was directed by Mark Waters and also starred Rachel McAdams, Lizzy Caplan, Lacey Chabert, Amanda Seyfried and Fey. The film centers on Cady Heron (Lohan), who returns to the U.S. from Africa and must adjust to high school life after previously being homeschooled. She soon must decide which social clique to be a part of and finds herself caught in the drama of “The Plastics.”
